- Structure: Their bodies are covered in feathers, they have wings for flight (in most species), lightweight and hollow bones, and a beak instead of teeth.
💡 Fun Facts
- Feathers: Feathers are an amazing structure unique to birds. They provide lift for flight, insulation to keep the bird warm, and are used for display to attract mates.
- Hollow Bones: A bird's skeleton is incredibly light but strong. The skeleton of a frigatebird, which has a 2-meter wingspan, weighs only about 115 grams—less than its feathers!
- Beak: A bird's beak is a specialized tool shaped for its diet. A finch has a short, strong beak for cracking seeds, while a hawk has a sharp, hooked beak for tearing meat.
